Application filed October 24, 1919. Serial No. 382,942.

of its objects being to provide means whereby steam is utilized for insuring a uniform feed of oil regardless of outside changes in temperature. 7

A further object is to provide a structure wherein the sight feed glass will not become I clogged. I

Another object is to provide a device which is simple, durable and compact in construction.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointedoutin the claim, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings the preferred form of the invention-has been shown.

In said drawings, I

Figure 1 is a central vertical section through the lubricator.

Fig. 2 is a section on line 2-2, Fig. 1.

Referring to the figures by characters of reference 1 designates a container for a lubricant, the same being provided at the bottom with a valved drain'2 and at the top with a steam condensing chamber 3 into which opens a steam pipe 4:. A gage glass 5. is connected by a tube to the top portion of the container, as shown at 6 and opens,

at its lower end, into a supply tube 7 which communicates with the bottom portion of I the'cont'ainer, as shown at 8. A valve casing .thecasing 10 through a tube 13 the inner end f 10 opens into the container 1 and has a steam inlet 11 which opens downwardly into a sight glass 12. A feed pin or nipple'12 extends downwardly into the'sight glass and is adapted to receive lubricant suppliedto of which terminates close to the top of the container 1. The lower end of the sight tube opens into a hollow plug 14 through which lubricant, heated by steam entering through the passage 11, will drop from the nipple 12 and flow outwardly by the pipe 15 extending from the drain outlet 2.

Steam condensing in the chamber 3 will flow down into the bottom portion of the container 1 through a tube 1 6 having a valve 17 for controlling such flow. The lubricant in the container will rise on'the surface of the condensed steam thus supplied to the container and will flow out through the tube 13 in small quantities, this lubricant being heated at the nozzle or nipple 12 as before explained. The level of the lubricant will at port-ion of the container, an inclined tube within the container for conducting lubricant from the upper portion of the container to the casing, a clean-out plug removably mounted in the top of the container and in line with the tube, asight glass engaged at is upper end by the valve casing, a nipple extending from the valve casing for directing lubricant therefrom and into the upper end of the sight glass, a valve for controlling the flow of lubricant through the nipple, means for directing steam into the condenser and into the valve'casing and aroundthe nipple and thence into the sight glass, a valved drain outlet in thebottom of the container, a pipe extending from the outlet, a hollow plug within'the pipe and opening into the lower end of the sight glass, said plug having openings in its walls in communication with the interior of the pipe.

In testimony that I claim the foregoing as in the presence of two witnesses.
